And even if you figure out which Points system module is the best, you still won't know which one is going to be the best in 3 years time. Or which one would even be working with the new DolphinPro.

As for rent-to-own, i think this may or may not be a good option for different cases. Some products would have to be paid for continuously (we expect even things like "maintenance service" or "media server hosting" to be offered), while some may well become "owned" after see more a while. I think it should be an option for vendor to choose and offer as part of the deal.
